Another 1911 Luger, DWM, markings on front rear of handgrip:

Attachment 96463Attachment 96464

I was told by the seller that 13 R.J. 54 indicates that the owner (Hauptmann Heinemann Presumably) was attached to the 13 Royal Saxony Infantry Regiment Jägerbattalion No. 54.

The unit markings stamped through, possibly the owner transferred?

Was it common practice to stamp the handgrip with the owner/unit?

Thanks!
